To all whom it may concern:

Be it known that I, l/VILLIA'M REINL, citizen of the United States, residing at Secaucus, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

This invention relates to an improved window sash fastener and has asone of its principal objects to provide 'a device of this charcter adapted to retain the sash, when elevated, at practically any elevation desired.

A further object of the invention is to provide a device which will be entirely automatic in its operation and which may be readily installed.

And the invention has as a still further object to provide a device which will in no way hinder the raising or lowering of the sash.

Other and incidental objects will appear hereinafter.

In the drawing:

Figure 1 is a perspective view showing my improved device in connection with a W111- dow of conventional design,

Fig. 2 is a fragmentary sectional view clearly illustrating the structural details of the device, and

Fig. '3 is detail perspective view showing the bolt and casing employed.

Referring now more particularly to the drawing, I have, for convenience, shown my improved device in connection with a wlndow of conventional design. The window casing is indicated at 10 and one of the sashes thereof at 11..

In carrying the invention into effect, I employ a rack 12 preferably formed of a suitable metal strip countersunk in one of the stiles of the casing so that the adjacent side rail of the sash 11 may readily ride thereover and securing the rack in position are screws 13. Formed in the rack is a plurality of substantially hemispherical sock ets 14 spaced longitudinally of the rack and entering each of said sockets at the upper and lower sides thereof is a pair of alined grooves or slots 15. As will be observed, the slots are arcuate in general configuration and the curved bottom walls of the slots of each socket form a continuation of the bottom wall of the socket, curving upwardly in opposite directions to the outer face of the rack. Set into the adjacent side rail of the Specification of Letters Patent;

outer ends'with oppositelydirect'ed lugs 17 countersunk in the rail. a Extending through these lugs arescrews 18 securing the casing n position. The casing is formed with a cylindrical inner wall and freelysl idable in the casing is a bolt 19. This bolt is, as best shown in Fig. 3, provided with a rounded outer end adapted to seat fiat in the sockets 14 respectively and extending diametrically of the outer end of the bolt is an arcuate runner 20 adapted to seat flat in each pair of the/slots 15. The runner may be integrally formed sash ll is an oblong casing 16 preferably square in cross section and provided at its on the'bolt or otherwise secured thereto and, as Wlll be noted,'the end portionsof the runner'overhang the bolt. Coacting betwen the inner end wall of the casing and the inner end of the bolt is a coil spring 21 and extending transversely through the inner end portion of the casing is a cross pin 22 with which the inner terminal convolution of the spring is engaged for holding the bolt against accidental outward displacement. v f

As will be readily understood in view of the preceding description, the spring 21 will urge the bolt to yieldably coact with the rack 12 so that when the sash is raised the bolt will drop into the sockets llsuccessively for retaining the sash elevated.

In this comiection, attention is directed to. the fact that, as shown in Fig. 2, when the flat in the pair of slots of said socketfor thus increasing the effective area of theouter end of the bolt coacting with the rack. Accordingly, the runner will assist in prevent ing accidental downward movement ofthe sash. However, when the sash is grasped and moved either upwardly or downwardly, the runner will ride against the curved bottom wall of'the corresponding. slot of the socket for lifting the bolt out of said socket, the runner sustaining the thrust of the spring 21 and moving the rounded end of the. bolt out of contact with the wall of the socket. Thus, as soon as the sash is started in either one direction or the other, the runner, will serve to readily ride the bolt out of any one vated. I accordingly provide a particularly effective device for the purpose set forth and one which may be readily employed in connection with practically any window using slidable sash.

Having thus described the invention, what is claimed as new is:

1. A sash fastener including a rack and a spring pressed bolt having a face to coact with the rack and provided with a runner projecting from said face to ride over the rack.

2. A sash fastener including a rack, and a spring pressed bolt having a face to coact with the rack and provided with a longitudinally curved runner projecting from said face to ride over the rack.

3. A sash fastener including a rack pro,- vided with a socket having slots leading therefrom, and a spring pressed bolt engageable in said socket and provided with a runner to seat in said slots.

4. A sash fastener including a rack provided with a socket having slots curving therefrom to the outer face of the rack, and

a spring pressed bolt engageable in said socket and provided with a longitudinally curved runner to seat in said slots.

5. A sash fastener including an element for attachment to a window casing, and a spring pressed means for attachment to a window sash having a runner to slidably coact with said element sustaining the tension upon said means.

6. A sash fastener including'a rack, and a spring pressed bolt formed at its outer end to coact with the rack and provided with an overhanging runner to ride over the rack. v p 7 7. A sash fastener including a casing, a bolt slidably mounted in the casing toproject therefrom and provided at its outer end with a runner, a spring within the casing behind the bolt urging the bolt outwardly, and a pin extending into the casing engaged with said spring securing the spring within the casing.

In testimony whereof I aflix my signature.
